To all "witam z't may conoern:

Be it known that I, GEORGE W. LILLY, a citizen of the United States,residing at Center, in the county of Rails, State of Missouri, haveinvented a new and useful Gravity- Hinge, of which the following is aspecifioation.

The object of my invention is to provide a hinge of novel constructionadapted to close the door by gravity; to provide a hinge so constructedas to support the door so that it will not sag; and to provide a hingethat will permit of the door being taken down without the removal of anyscrews.

It is further my object to provide a hinge that will allow the door tostand open when pushed beyond ninety degrees from the closed position.

It is an especial object of my invention to eliminate the necessity forsprings to close the door.

It is also an object of my invention to provide a hinge that can beregulated easily as to its closing qualities. v

I attain the objects of my invention by the mechanism illustrated in theaccompan fing drawings, in which- Figure 1 is a view of my inventionap'f plied to a door; and Fig. 2 is a detail horizontal sectional viewof the hinge.

Like characters of reference designate like parts in each of the views.

Referring to the accompanying drawings, 2 designates the door and 1 thedoor frame. A hinge rod 7 is secured to the door frame by suitablestraps 8 and fastening` members 4. I provide bifurcated lever' 9 havingits outer end portion extending slidably through the screw-eye 14 whichis fastened to the approximate center of the door, as illustrated. Thehooked end 10 of lever 9 is slidably engaged about hinge rod 7. Thelower arm 11 of the bifurcated lever has a downwardly turned end 12engaged in an aperture 13 of the L-shaped plate 5 in its outturnedportion 6 at a point substantially beyond the hinge rod 7 as illustratedin the drawings. It is Within the contemplation of my invention tochange the position of 7 and balance the door. When the door is releasedits weight bearing` on the bifurcated lever 9 will cause the door toswing to its closed position, this operation resulting from the offsetposition of the end 12 of arm 11 of the lever 9 relative to the positionof hooked end 10 of the other arm of the lever, which engaged abouthinge rod 7. I may change the position of aperture 13, and thus modifythe inclination of lever 9, which will modify the operation of thegravity hinge accordingly. The door will stand open when pushed past theright angle are, or substantially beyond 90 degrees from closedposition.

It is within the contemplation of my in- Vcntion to apply my hinge todoors of all kinds, and especially to screen doors, barn doors andgates.

vWhat I claim is:

In a gravity hinge, the combination of a door frame having asubstantially Vertical rod mounted thereto, a door having strap membersslidably engaging the aforesaid rod, a bifurcated lever having a loopedarm slidably engaging the rod and having a second arm engaging a memberattached to the door frame at a point substantially beyond the rod, theaforesaid member aiixed to the door frame, and a member afiixed to thedoor through which the end of the bifurcated lever projects.

GEORGE W. LILLY.
